The effect of a force acting over a period of time

Question 2

What is the measurement for an impulse ?

Answer 2

Newton seconds

Question 3

How can an impulse be used to increase momentum ?

Answer 3

• can happen through increasing muscular force
• E.g. Basketball: Larger force is generated for a higher jump
• Can also happen through have an increased time that the force is allowed
• E.g. Hammerthrow: Using 3/4 spins rather than just a single rotation

Question 4

How can an impulse be used to decrease the momentum ?

Answer 4

• by increasing the time forces act upon them

Question 5

What is a net impulse ?

Answer 5

A combination of positive and negative impulses
